Miniature rose plant named &#39;Savabusy&#39;

ABSTRACT

A new and distinct Miniature Rose plant having attractive predominately orange flowers.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a new and distinct variety of rose plant of the Miniature class. The new variety was created by crossing as seed parent the variety known as ‘MORSEGOLD’ (U.S. Plant Pat. No. 6,617) and as pollen parent, the variety known as ‘SAVASPARK’ (U.S. Plant Pat. No. 9,799). The varietal denomination of the new variety is ‘SAVABUSY’.

SUMMARY OF THE INVENTION

[0002] Among the novel characteristics possessed by the new variety which distinguishes it from its parents and all other varieties of which I am aware, is its flower shape and flower color.

[0003] Asexual reproduction by propagation of vegetative cuttings of the new variety as performed in Essex County, Massachusetts show that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagation.

COMPARISON WITH PARENTS

[0004] The new variety may be distinguished from its parents in its form and flower color.

[0005] The new variety has predominately orange flowers whereas the flowers of its seed parent, are yellow and the flowers of the pollen parent are medium red.

COMPARISON WITH RELATED VARIETIES

[0006] In addition to the foregoing, the new variety also differs from other cultivars of the same cross.

[0007] The first is ‘SAVABINO’ (U.S. Plant Pat. No. 10,980), ‘BAMBINO’) which is overall a considerably smaller plant with smaller blooms of a deeper orange red coloring.

[0008] The second is ‘SAVAPPLE’ (U.S. Plant patent application Ser. No. 09/727,065, filed Nov. 30, 2000) which is a lower growing plant and although the open blooms are about the same size, ‘SAVAPPLE’ has about half as many petals as this new cultivar and also is more red in its coloring.

BRIEF DESCRIPTION OF ILLUSTRATION

[0009] The accompanying photograph illustrates a typical specimen of the new variety and shows the flowering thereof from bud to full bloom depicted in color as nearly true as it is reasonably possible to make in a color illustration of this character. Throughout this specification, color references and/or values are based upon The Royal Horticultural Society Colour Chart and terminology used in the color descriptions herein refers to plate numbers in this color chart except where common terms of color definition are employed.

DESCRIPTION OF THE NEW VARIETY

[0010] The following observations were made of 6-year old plants of the new variety grown outdoors, in 8 inch standard pots, in Essex County, Massachusetts during the month of September. Phenotypic expression may vary with environmental, cultural and climatic conditions, as well as differences in conditions of light and soil.

[0014]Permanent.—Yes.

[0015]Hip/Stem position.—Rolling back to stem and remaining thus and attached to the receptacle Peduncle: Peduncle with receptacle and sepals die and remain attached to plant Length: About ¾ to 1 inch Aspect: Straight Strength: Erect Color: Near 144A, side facing sun may be flushed with 187C Texture: Extremely fine hairs.
